I partially agree with this, I think USF needs general classic Halloween decor throughout no matter what the event's theme is each year.
I say keep the Central Park, New York and Hollywood scare zones, but decorate the rest of the park with more traditional Halloween decor. Go all out in 3 zones & possibly expand the NY zone into some of the side streets. With the lack of house portals at Kidzone, the Central Park zone tended to be enjoyable at times compared to previous years. I still think they can work with this zone.
Considering that there's really only been 2-3 HHN-worthy zones each year, it won't feel like a decline in experience.
